So, evidently, McG had never heard of this "Terminator" stuff, some crap from the 80s or something, so they told him to go rent the video, but he ended up checking out Road Warrior instead, because it was on the same rack, and was too embarrassed to tell them about the mistake, and besides, that was one kewl movie. Then they all saw Batman and thought that was one kewl movie too, and totally decided they wanted that actor, whoever he was, and not realizing that he was the dead one, so it ended up starring Christian Bale instead.
